The present invention relates to a novel electronic device. In detail, in an electronic device having an input display unit which combines an input operation surface and an information display surface and a signal processing circuit for processing a signal input from the input display unit, the input display unit is made compact to improve operability.

The electronic device of the present invention is provided with an input display unit in a first box, a signal processing circuit is installed in a second box, and the first box and the second box are connected by a rotation connecting member. The second display body is rotatable between the first position at which the second box body covers the input display portion and the second position at which the input display portion is exposed to enable the input operation. Covered by the box 2, the risk of damage or the like is eliminated, and since the input display unit is provided in a separate box, the shape thereof can be made small and the input operation can be easily performed.

Electronic devices having an input display unit that combines an input operating surface and an information display surface, for example, a word processor or an author's notebook, have been proposed.

These electronic devices are provided with an input display section on an upper surface of a box housing a signal processing circuit or a power supply section.

However, in the electronic device described above, since the input display portion is exposed to the upper surface of the box, there is a high risk that the input display portion is broken, for example, there is a problem in carrying it by hand.

In addition, since the signal processing circuit and the power supply unit are housed in one box, the box becomes large, and in particular, when the plane shape is reduced, the thickness becomes large, and the input operation, especially the handwriting input using the input pen, is very difficult. There is a problem.

In order to solve the above problems, the electronic device of the present invention is provided with an input display unit in a first box, a signal processing circuit in a second box, and a first box and a second image. It connects itself with a rotation connection member, and makes it rotatable between the 1st position which a 2nd box covers an input display part, and the 2nd position which enables input operation by exposing an input display part.

Therefore, in the electronic device of the present invention, since the input display portion is covered by placing the second box in the first position, the input display portion is not easily broken, so there is no danger of carrying it in this state. This is improved. In addition, since the input display unit is provided in the first box body by dividing it from other parts such as a signal processing circuit, the first box body in which the input display unit is provided can be made compact and particularly thin, so-called handwriting input system. The operation of the input operation in the case of adopting the above is remarkably improved.
